The position is funded through a cooperative agreement with the Earth System Science Interdisciplinary Center (ESSIC) at the University of Maryland, but the primary work location is on the Goddard campus. Career-growth opportunities include the possibility of interacting with a broad range of NASA scientists with skills in Earth observation, atmospheric transport and composition modeling, and high-performance computing.

The Atmospheric Chemistry and Dynamics Laboratory at the NASA Goddard Space Flight Center in Greenbelt, MD, is looking for a scientist to support aerosol modeling and analysis work using the GEOS Earth System Model (ESM) and making extensive use of NASA observations. The GEOS ESM includes various aerosol codes, including bulk, sectional, and modal representations. We are looking for a scientist to work at evaluating and improving these aerosol representations, including their microphysical and optical properties, and to enhance integration of aerosols with other Earth system components, such as gas phase chemistry, radiation, and moist physics. Specific tasks include code testing and validation, comparisons of different mechanisms within the GEOS system, and usage of NASA remote sensing, in situ, and airborne data to evaluate model performance. High priority activities include enhancing aerosol-gas phase chemistry coupling, aerosol-cloud-radation interactions, and improvement of the representation of aerosols in the Upper Troposphere and Lower Stratosphere to support NASA’s OMPS LP and SAGE III/ISS missions. The work primarily supports the GEOS Chemistry-Climate Modeling (CCM) effort and offers the opportunity to join a large and active community working on a big model in a collaborative environment. Additional opportunities include making important contributions to modeling of aerosols in the GEOS near-real time forecasting and data assimilation system in collaboration with our colleagues in the Global Modeling and Assimilation Office.

Qualifications:

The position is designed for an early to mid-career scientist with experience working with Fortran code in large modeling systems and with a background in atmospheric aerosols and chemistry.

Must have PhD in atmospheric sciences or similar. Working knowledge of three-dimensional aerosol/chemical transport models. Fortran coding skills required, work in a high performance computing environment highly desired. Background in atmospheric aerosols or atmospheric chemistry.

To Apply: Interested candidates should send a CV with a list of at least 3 professional references and a cover letter explaining how your qualifications meet the posted requirements to anegri@essic.umd.edu.
